Toward the end of each school year, students in metro Atlanta’s public school districts take a series of tests to determine how much and how well they learned during that year. Students in elementary and middle schools, or first through eighth grades, take Criterion-Referenced Competency Tests (CRCT), and students in high school, or ninth through 12th grades, take End-of-Course Tests (EOCT).

Below are the elementary, middle and high schools in each of metro Atlanta’s public school districts whose students performed best on the tests, according to data on schooldigger.com, a website that evaluates K–12 performance. Elementary and middle schools were ranked based on math and English/language arts scores on CRCT and high schools on American Literature and Geometry scores on EOCT.
